APPLICATION FILED OCT. 6. I919 UNITED STATES CHARLES F. JORDAN, OF NEWYORK, N. Y.

CAR-DOOR LOCK.

Specification of Letters Patent.

Patented Dec. '7, 1920.

Application filed October 6, 1919. Serial No. 328,694.

To all whom z'tmay concern:

Be it known that I, CHARLES F. JORDAN, a citizen of the, United Statesof America, residing at New York, in the county of New York and State ofNew York, have invented certain new and useful Improvements in Car-DoorLocks, of which the following is a specification.

My present invention relates generally to car door locks, and moreparticularly to the practical application in use of that type of cardoor lock embodying a seal, as shown in the application of JohnMacKenzie, Serial No. 289,325, which was filed April 11, 1919, my objectbeing the provision of a practical, simple and durable mountlng for thelook, as well as to provide against 1mproper opening of the lock in sucha way as to mutilate any of its parts.

A further object is the provision of means which will prevent improperopening of the lock and will in addition serve to provide for the use ofa supplemental ribbon seal as now commonly used in connection withfreight car door locks.

With the above in mind, my invention resides in certain features to behereinafter particularly pointed out. among those which I will nowdescribe, with respect to the accompanying drawings, forming a part ofthis specification, and in which Figure 1 is a side elevationillustrating the practical application of my invention,

Fig. 2 is a front elevation of the lockand its mounting removed,

Fig. 3 is a vertical longitudinal section taken substantially on line 33of Fig. 2,

Fig. 4 is a horizontal se tion taken substantially on line 4 -4 of Fig.1,

Fig. 5 is a partial horizontal section throu h the stop plate or lockmounting taken along a line above the bolt housing, and

Fig. 6 is an elevation of the bolt lock member removed.

Referring now to these figures. mv invention is proposed in connectionwith a lock of the type including a chambered housing 15 through whichthe verticallv shifting lock bolt 16 reciprocates. This bolt has anupper protecting cap 17 which in the lower effective position of thebolt, rests upon the top wall of the housing and covers a slot 18through which a pan-shaped seal 19 may 7 be introduced when the bolt iselevated.

Thus the cap 17 in its effective position prevents the entrance of rain,snow or other extraneous matter within the housing.

"When in position within the housing forwardly of the locking bolt 16,the seal 19 rests upon an inner shoulder of the housing, and the housingbase like its top wall has guide openings for the bolt, and the seal ispositioned forwardly of a spring bolt looking member 20 which is hung ona transverse pin 21 and which has two downwardly diverging wings, theouter or forward wing of which bears against the seal 19 and the rear orinner wing of which engages a notch 22 of the bolt 16, when the latteris thrust downwardly to locked position.

The housing 15 is open at the front and the seal 19 normally covers thisopening so as to prevent access to the bolt locking mem ber 20 untilafter the seal is ruptured.

In its lower locked position, the locking bolt 16 projects beneath thehousing 15 and through an apertured ear 23 which forms a staple andwhich receives the door carried hasp 24: thereover, and the lowerextremity of the bolt 16 is slotted as at 25 for the re ception of theusual ribbon car seal 26, shown in Fig. 1.

In accordance with my present improvements, the lock housing 15 ismounted on and integral with a door stop plate 27 which forms the lockmounting and which is preferably a casting having three sides to adaptthe same to fit over the inner ends of the door stop strips 28 of a carside, which the casting overlaps sufficiently to receive bolt 29 throughits openings above and below the lock housing 15.

The lock mounting or stop plate has a brace or bracket arm 30 projectinglaterally therefrom at one side to receive a bolt 31 through the carside and has an oppositely gxtending intermediate door engagingFurthermore, and in accordance with my present improvements the lockmounting or stop plate 27 has an outstanding lug 33 below and spacedfrom the staple 23, which is arranged in the vertical line of the lockbolt 16 and projects from the stop plate slightly beyond the plane ofthe lock bolt. The lug 33 is furthermore so positioned with respect tothe lock housing and the length or the bolt 16 as to receive the lowerfree end of the bolt thereagainst in the lower locked position of thebolt in order to prevent the use of a hammer or other tools against thelower end of the bolt for the purpose of forcing the latter verticallyto released position without first rupturing the seal 19 and releasingthe bolt by swinging the spring locking member 20 in an outwarddirection.

It is obvious that although the bolt could not be forced vertically toreleased position, while the seal 19 is in place, without showingevidence thereof, careless persons might, rather than rupture the sealand spring the locking member outwardly, simply force the boltvertically, which would itself rupture the seal in all probability andwhich would obviously ruin the spring locking member 20.

With the lug 33 in position, the bolt cannot be struck and forcedvertically to released position or pried upwardly. The lug also serves afurther function by virtue of its provision with an inner verticallyextending shoulder portion 34: inwardly be yond the plane of the bolt 16with respect to the stop plate or mounting 27 which shoulder portion hasa slot 35 thus arranged to aline horizontally with the slot of the lowerend of bolt 16 for the reception of the usual ribbon seal, supplementingthe seal 19 above described.

The above described mounting for the lock and my improvements inconnection therewith are designed to fulfill all require ments for thepractical introduction of car door locks of the above type,and'obviously avoid disadvantages due to carelessness which would arisein its practical operation.

I claim V 1. A car door lock comprising a mounting or support, a lockingmechanism thereon including a vertically movable locking bolt providedwith a seal receiving slot adjacent to its lower free end, and a sealcontrolled spring locking member engaging the bolt in its lowerposition, and a lug carried by the said mounting or support in line withthe bolt, receiving the free end of the bolt in abutting relationthereagainst in the locked position and provided with a shoulderinwardly beyond the plane of the bolt having a slot to cooperate withthe bolt slot for the reception of a seal, as described.

2. A car door lock comprising a supporting plate, a locking mechanism onthe plate including a lengthwise movable locking bolt having a slotadjacent to its free end and shiftable in parallel spaced relation tothe plate and a seal controlled spring locking member engaging the boltin its lower position, and a lu carried by the plate in line I n n I vwlth the axls of the bolt said lug prqectmg from the plate beyond theplane of the bolt and positioned to receive the free end'of the bolt inabutting relation when the bolt is in locked position, and having aninner shouldered portion located between the supporting plate and theplane of the bolt, provided with a transverse slot arranged parallel tothe adjacent face of the supporting plate to cooperate with the boltslot as and for the purpose set forth.

In testimony whereof I aflix my signature.

CHARLES E. JORDAN.
